Introduction and motivation

We have been living with COVID-19 for a long time since the beginning of 2020, as of 1 September 2021, more than 218 million cases and 4.52 million deaths have been confirmed, making it one of the deadliest pandemics in history. Besides that the pandemic has resulted in severe global social and economic disruption, including the largest global recession since the Great Depression of the 1930s.

Therefore, the analysis of the virus is very valuable. In this blog post, I will first introduce the basic knowledge of the virus and then focus on the current situation of COVID-19 in the Poland.

What is Covid-19

The COVID-19 pandemic, also known as the coronavirus pandemic, is an ongoing global pandemic of coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

COVID-19 symptoms range from unnoticeable to life-threatening. Severe illness is more likely in elderly patients, as well as those who have certain underlying medical conditions. The disease transmits when people breathe in air contaminated by droplets and small airborne particles. The risk of breathing these in is highest when people are in close proximity, but still present over longer distances, particularly indoors. Transmission can also occur if splashed or sprayed with contaminated fluids in the eyes, nose, or mouth, and, rarely, via contaminated surfaces. People remain contagious for up to 20 days, and can spread the virus even if they do not develop any symptoms.

Data description

There are three datasets be used in this post one is from Rami Krispin (2021) ,European Centre for Disease Prevention and Control (2021) and owid’s github (2021).

The first dataset was downloaded from the Github repository of RamiKrispin’s github Repository. This dataset has 496488 number of observations and 7 number of variables. It is about the number of cases which is confirmed, recover or dead beacuse of covid-19 in each country, it cover the data from 2020-01-22 and Hopkins University (2021) updated on a daily bases. Because of it we can get the newest information from it. The raw data pulled from the Johns Hopkins University Center for Systems Science and Engineering (JHU CCSE) Coronavirus repository.

The second dataset was maintained by European Centre for Disease Prevention and Control. This dataset has 85435 number of observations and 12 number of variables. It is about the data on COVID-19 vaccination in the EU/EEA and updated twice a week (every Tuesday and Friday). This data covers data from the 52nd week of 2020 to the 37th week of 2021.

The third dataset is from owid’s github Repository. This dataset has 117021 number of observations and 62 number of variables. It covers information on diagnoses, hospitals and government response capacity in each country. It is also updated daily. This data covers data from 2020-01-01 until now.

Data Limitation

The raw data, especially the data from Rami Krispin (2021) and owid’s github (2021), may be due to statistical techniques, government policies, etc., some of the data in some countries are empty. I ignored these null values in my analysis.

In addition, I found some mistakes when using the data, for example, some numbers that should not be negative were counted as negative numbers, and I chose to convert them into positive numbers in the analysis below.

Global overview

From table 1, We can see that globally, as of 2021-09-15, there have been227055138 confirmed cases of COVID-19, including 4670253 deaths, reported to WHO. COVID-19 has already caused us so much loss and pain.

Figure 1: Global map about comfirmed and death cases on 2021-09-15

(You can select the data type you want to see in the upper right pane. Put mouse on each circle you can see the detail about country names and the number of them.)

The figure 1 show us the reported cases on 2021-09-15. In terms of daily numbers, the main confirmations of late have been in America, Europe or South-east Asia. Perhaps due to differences in government policies, culture, surveillance, accuracy of reporting and so on, the number of confirmed cases in east Asia and Africa is relatively low. The distribution of death data also roughly matched that of confirmed cases.

Covid-19 in Poland

Poland, officially the Republic of Poland,is a country located in Central Europe. It is divided into 16 administrative provinces, covering an area of 312,696 km2 (120,733 sq mi), and has a largely temperate seasonal climate.Poland has a population of nearly 38.5 million people, and is the fifth-most populous member state of the European Union.Warsaw is the nation’s capital and largest metropolis.

The following analysis focus on Covid-19 in Poland. The Poland has seen a recent decline in cases of COVID-19 infections and deaths, possibly due to previous restrictions. But some recent policies, such as the opening of tourism and entertainment venues, still increase the potential for a rebound. Below, I would like to present an overview of the development and current situation of COVID-19 in Poland from two aspects: infection and vaccination.

Story1 : Covid-19 Cases in Poland

In this section, we can see the development of the number of CONFIRMED COVID-19 cases, deaths, recoveries and virus tests in Poland.

Figure 2: Cases in Poland

The figure 2 show us the trend of COVID-19 diagnoses, deaths and recoveries in the Polannd. In general, all three values experienced two peaks, in November and December 2020 and March and April 2021. And the number of deaths and recoveries peaked later than the number of confirmed cases.

Overall, the recovery rate from COVID-19 is still relatively high. However, the death data and recent rebound in diagnoses cannot be ignored. Are these figures reliable? Are there many people who have not been tested for COVID-19? Below is information on virus testing and diagnosis rates.

Figure 3: Daily tests vs. Daily new confirmed cases per million

(Each dot represents a country, you can use the mouse to explore the specific value of each dot, the red dot represents the Poland)

This graph 3 shows the average number of COVID-19 tests and diagnoses per million people in Poland. Of all the countries, Poland’s testing rate was very low, about 1,038 tests per million people, but the number of confirmed cases reached 158. Overall, compared with other countries, the number of confirmed rate in Poland is relatively high. But it also shows that Poland’s tests may not have been enough.

The main effective response to COVID-19 right now is a vaccine. Below is information about vaccination in Poland.

Story2 : COVID-19 Vaccination in Poland

Table 2: Vaccine Uptake rate in Poland
vac_dose_rate full_dose_rate
57.96002 43.40534

This table 2 shows Poland’s vaccination rates to date. More than 50 percent of the population has been vaccinated, and more than 37 percent have been full vaccinated. In contrast, the first vaccination rate in the European Union has reached 66 percent, and 60 percent of the population has been full vaccinated. Poland still needs to increase the number of vaccinations.

Below is a chart of the total number of vaccines received per week.

The number of vaccinations

Figure 4: The number of vaccinations

The figure 4 shows the trend of vaccination in the Poland.

Here are the weekly numbers, and we can see the percentage of people choosing different brands of vaccine.

Figure 5: Number of weekly COVID-19 vaccinations by each brand

The figure 5 shows the vaccinations from 2021-08-23 to 2021-08-29, and we can see the brands that people were vaccinated with last week.

Conclusion

COVID-19 is still raging around the world today and has taken a huge toll on humanity.

In Poland, although the number of confirmed cases has decreased recently, there are still a lot of new cases every day, still need to pay attention to.

While the virus is still raging, there are some hopeful signs that this health crisis will end. Countries are succeeding in containing the virus using social-distancing practices, testing, and contact tracing, at least for now, and treatments and vaccines may develop sooner than expected.

I hope all of us can establish a correct understanding of the virus, not too panic, but also actively protect ourself and pay attention to the information around us.
